    Going Fitech what about timing?
    « on: April 21, 2018 - 06:17:16 PM »
    Hi, We are looking to go Fitech road and been reading all the post I could find on the subject. We are going to get a mecanic at a speed shop with a good reputation. The 340 is all stock and run good. We are not looking for more power, so we would go with the Go street 400Hp and a EFI ready tank from Tank inc. What about the timing and fire do we keep everything stock? With the Fitech what hapen to the choke? Does the OEM alternator give enought power, it as been rebuilt in new?

    Timing is the same as stock, you have to set it manually as the Fitech doesnt control or alter it.

    As to the choke, the Fitech controls this through the provided senor/s

    as far as your alternator goes, depends on what size and what electrics you have in your vehicle. EFI likes good strong clean power but you dont need anything crazy. If you are running a 60A alternator without HID lights, big stereo, etc. you should be ok but on the bottom end.

    Remember to connect the EFI directly to the battery as stated in the instructions, do not let your mechanic try and convince you otherwise.

    The 400hp version does nothing with timing, the ignition stands alone just like before.

    I’m thinking of going Fitech also, interested in any and all info on this.

    As far as timing I’m thinking it’s not going to change much if any if yours is dialed in now.
    For fire are you asking about upgrading ignition/distributor?  I have the factory electronic with orange box, many like it and you would probably be fine with it. I’m looking at GM HEI using 8 pin module. Google HEI conversion. https://www.forabodiesonly.com/mopar/threads/hei-in-mopar.86816/. This seems to be a bit better than stock Mopar.

    Problem with older OEM alternators is low volt/amps at idle/low RPM’s.
    You may want to upgrade your alternator, see what your loads and/or future loads will be with this calculator. Thanks to Brads70 for finding this http://www.qualitypowerauto.com/pages/AmperageLoadCalculator.php
    If you haven’t already do an amp meter bypass.
    I’m switching to a Denso or GM alternator because they provide more power at idle/lower RPM’s.
     I added 20% to my amp total so the alternator isn’t maxed out.

    I installed a Fitech Go Street on my 52 Dodge PU and I have to say it couldn't be easier and having installed a Holley system prior to that I have a good base of comparison. Its like all of 4 wires. The truck fired the first time and quickly went to an very stable idle. Throttle response was/is really good and the truck never ran as good as it does with the Fitech. I removed a relatively new Holley 650 but because the truck sits most of the time, it was having issues maintaining an idle, surging and generally running like crap. I didnt touch the distributor at all, hardest part was installing the fuel system which wasn't too hard.

    On an E body, the fuel system is pretty easy depending on what you want to do for fuel lines. When put the EFI on the Challenger I installed a new Tanks Inc. tank and pump and then bent new aluminum 1/2" lines. Don't forget the filter, you will need 100 micron on the feed side.

    I have installed a 600hp version w/timing control on a 1979 Li'l Red Express. So far it's been pretty good, fired right up and idled.

    We've been tweaking from there, it has about 800miles on it.

    Thanks every body. 70chall440 we are going EFI for the same reason the challenger sit for long time and its hard to keep the carb running good. Has for the electrical load every thing original except when the guy that that rebuilt the alternator told us that he rebuilt it stronger. In a near futur we are plannig on doing the amp meter bypass and buy the relay kit for the headlights. Since it a 1970 no orange box, so should we do something there?

    Nel - yes, I went EFI 6 pack on the Challenger bc it sat for long periods and I was tired of rebuilding the 6 pack carbs. The system I have on the Challenger is much more complex than the Fitech as it controls spark, timing and fuel so there are a lot more wires and more things to install. I am running a MSD 6AL ignition with a Holley dual sync distributor.

    As for the alternator, I am running a Nippo Denso out of something like a 90 Dakota which is a 120 amp unit. I am running HID headlights and have a relay system installed. I eliminated the Amp gauge a long time ago.

    Does the OEM air filter fit on the FItech 400?

    can you just put in a 3/8"x 1/4" sending unit for your return line instead of a bung in the tank?

    Are you asking if you can eliminate the return line? If so, no you need a return line.

    I should  probably start another topic. But I will keep posting my question in this one if it okay. Reading the install instruction on the Fitech Go street EFI 400. Here what it says : 

    Fuel Delivery Systems:
    You may have chosen one of the
    two optional Fuel Delivery System Kits from FiTech. In-
    structions come with each kit. If using other fuel delivery
    components you must use a 30-micron filter ahead of the
    fuel inlet fitting on the Fitech throttle body. 

    So if I use a EFI ready tank from tank inc with their GPA-4 pump and TAN-ORG sending units like Tank inc tech told me.
    I still have to put 30-micron filter in the line?
    If yes what you guys use and where you mount it? Does it have to be close to the throttle body or anywhere on the line?


    Also they say :

    If you choose to use some other fuel delivery system
    other than FiTech, it is important to make sure that you
    confirm its compatibility with the FiTech EFI system. Con-
    tact the FiTech technical staff to check compatibility. Fail-
    ure to do so can void your warranty.

    I wrote 2 e-mails telling them that I was planning on using a Tank inc system and ask them if it was okay no answer. Put the tech from Tank inc seem to know it working he the one that give me the list of all the correct parts that I needed.
    Looking a those you guys think it all right?
    Do I need their straps, mine are new but I dont know if they will fit?

    I would suggest using the LS style filter so you don't need a return line from the front to back....

    https://www.ebay.com/itm/C5-Corvette-Fuel-Filter-Regulator-Fittings-58-PSI-for-LS-swap-ships-free-/183057271223

    Also FWIW the sending unit your showing is a PITA.. I know, I have one...  Rather than getting the float style consider getting a floatless one

    Cool so No need of a return line from the front to the back. Just a short one from the filter to the tank? I dont know mutch about the PSI required the one you suggest would be alright at 58 PSI? In the instruction of the Fitech they says the system run at 58 PSI so suppose it would be alright. Sorry if I ask alot and look stupid but I want to know as mutch as possible and get it right the first time. In a another post I have read that heaven with the command center you end up having to put a return line.
